Siebenuhr Mk I User Guide

Initial Setup

1. Connect power — Plug the power adapter into the controller box, then into the wall. The clock has no power switch and will wake up immediately, displaying "7uhr".

2. WiFi setup — After a few seconds, the clock displays "WiFi" and creates an access point called SiebenuhrAP.

3. Connect to the access point — Use your phone or laptop to connect to "SiebenuhrAP". A configuration page should open automatically.

4. Configure WiFi — If the page doesn't open, go to http://192.168.4.1 in your browser. Select "Configure WiFi" and enter your network name and password.

5. Done — After saving, the clock connects to your network, fetches the time via NTP, and starts displaying the current time.

Installation Tips

• The controller box cable is 1.6m — plan placement accordingly
• For thin walls with rear access, cables can be hidden by drilling through
